- **edit - Hi Everyone - specific to 6:45 - to advance the timing, the plate is rotated in the opposite direction of the engine rotation - to retard the timing, the plate is rotated with the engine rotation- sorry guys!**
Hello Everyone!
Whether you grew up with them, or you're just getting into classic engines, you're going to come across ignition points at one time or another!
A purely mechanical ignition trigger system is made up a lot of components that have to work together properly in order for your engine to run.
This video will guide you through a quick run down of how to set the initial timing on your points in order to get your motor running so you can fine tune everything with a timing light.
For those that read the description - Don't worry - Miss Vicky will be back next episode!!
Hope you all enjoy and as always, thank you for watching!

Dont forget to sub if you havent already for more to come!
Right on
Thanks
The Best video on this subject really , many thanks !
This is a counter clock wise points mechanism with advance ? Is it invincible to fit same with a two points system on a TDM 850 on the left hang side note two piston are tdm at same time any body have an answer.
Hey Rick, I love your videos, I have a problem timing my 77 xs750, the Mark's will not line up no matter what I do, All 3 points open about halfway between the Mark's, I'm suspicious a previous owner moved the index pointer. How do I varify it's in the correct position?
Hi Mudder - thanks for your comment! Sorry to hear you're having trouble- I'd verify the governor wheel is aligned correctly to the crankshaft first - (check the 3:00 mark of ep. 24) - if everything looks good, pop the valve cover to verify valve positioning to get cyl #1 (left side)to TDC. Once TDC is confirmed, check the pointer- it should be aimed at the "T" on the timing wheel. Adjust the pointer as necessary. Once #1 is set, confirm the correct positioning of the pointer for the two other cyl at TDC also.
Hope that helps!
Struggling with my 79 xs750 triple. I can't seem to sync #1 point to open correctly. It wants to open on the #2 point or there about. I've gapped all the points correctly and moved the plate to both extremes to see if it would change anything but nothing? What am I missing?
The only thing that comes to mind is the center cam that operates the points. Is it perhaps mounted 180⁰ on the timing wheel?
I've got roughly the same issue, did you ever find a solution? I've taken it all apart and the center wheel is mounted correctly as it can only mount one way but im still not on target.
Tengo un moto xs 750 honda era de platinos la quisieron convertir a ensendido más moderno y no prende, pero me quedaron la tapa original del estaré o bobinas y mesesito está pieza si pudieras de ir dónde la consigo y si emsendera con lo electrovo
My best suggestion if you're having trouble with an aftermarket ignition conversion is to contact the supplier/manufacturer. Dynatek seems to be the biggest name in ignition conversions for Honda 750s. Try contacting them at www.dynaonline.com. They may be able to steer you in the right direction.
Mi mejor sugerencia si tiene problemas con una conversión de encendido del mercado de accesorios es que se comunique con el proveedor / fabricante. Dynatek parece ser el nombre más importante en conversiones de encendido para Honda 750. Intente contactarlos en www.dynaonline.com. Es posible que puedan guiarlo en la dirección correcta.
What's the worst that could happen if one were to ream the adjustment plates for 2 and 3 a touch to get the smidge of advance needed? Currently had to retard #1 to get 2 and 3 closer
I'd say the WORST that could happen would depend on how close to the edge of the slot is opened up to. If it's really close to the edge, the plate could vibrate loose and lose the timing.
@@RicksGarage I'm only off by a sliver but I think I'll track down a donor plate to experiment with

Nice video. BUT you don't turn the point plate in the direction of rotation to advance the timing, you turn it that way to retard the timing. #2 you are not explaining the advance mech. Some engine's timing marks are meant to be adjusted with the advancer all the way advanced.
Sonofagun! I can't believe I scripted that in reverse! I must've watched the draft 10 times and still missed it. Thank you Ted for pointing that out. I've updated the description with the correction.
Left hand side, and TDC, sorry
You advance it by turning it opposite the engine rotation
Yikes you bought the 1977 mistake. Those points will kill your engine faster than low oil. Yamaha knew this in one year.
